Firm offer or clearing?

Hi guys just a little context I’m a medicine applicant who achieved AAB and these r my resit grades (I’ve already taken a gap year). My firm choice, Liverpool gave me an unconditional to study biomedical science instead of medicine. But my insurance choice has a biomedical degree that allows transfers in the first year to medicine. Because I initially applied for medicine, this would mean I would have to decline my offer at Liverpool, go to clearing and apply for biomedical science at Plymouth. But, I don’t know what I should do because to be honest I really am just doing this to get into medicine. Both options are very competitive with GEM and the transfer only allowing 10 students who have to achieve 70%+ on all the modules. I’m really stuck any advice would be greatly appreciated!
